Using Outlook for Android in business environments for email and scheduling
Hi
I have same issue with login to me mail server with neu Outlook App.
Finally I desidetet to find neu app - K-9 Mail, witch was worked in few minutes..
But after hours fight I decided to tell Your what I think goes wrong with outlook app.
My server use STARTTLS what can't be chose on this app. I also noticed that my email domain must be the same like as, my server domain, unfortunately one of my email address isn't. I hope that will be useful. Greeting.
